INSULAT'INGr-ROSETTE FOR ELECTRIC-LIGHT FIXTURES.

To all whom it may concern:

Be it known that I, NIELs LANG, citizen of the Dominion of Canada,residing at Vancouver, in the Province of British Columbia, Canada, haveinvented a new and useful Insulating-Rosette for Electric-LightFixtures, of which the following is a specification.

This invention relates to an insulating rosette such as is used inconnecting the wires of an electric light circuit to a chan- I delier orthe like, and is designed to dispense with the necessity for solderingand taping the wire of the chandelier lamps to the service wire byproviding binding screws to which the connection may be made, saidbinding screws being so placed as to be easily accessible for thepurpose.

The invention comprises the provision of an insulating rosette having acentral aperture through which the tube may pass by which the chandelieris suspended from the crowsfoot, or from the insulating joint of aconduit system, the rosette being of such form that the binding screwsare angled outward to enable a screw driver to be more convenientlyapplied to them when the bell canopy is slid down the suspension tube toafford access to the rosette.

The invention is particularly described in the following specification,reference being made to the drawings by which it is accompanied, inwhich:

Figure 1 is a section of the device showing its relation to thechandelier suspension and the bell canopy by which the connection iscovered. Fig. 2 is an enlarged section of the insulator rosette on theline A A in Fig. 3, and Fig. 8 is a plan of the underside of the same.

In these drawings 2 represents the crowfoot by which the suspension rod3 of a chandelier or the like is connected to the ceiling. Fitting onthis suspension rod 3 and retained in contact with it by a collar a orby the outer casing tube 5 of the chandelier, is an insulating rosette 6the rod or stem 3 passing through a central aperture 7 of the rosette.This rosette is provided with the usual terminal plates 8 having bindingscrews 9 for connection of the wires 10 of the circuit and 11 of thelamp. Service connection may thus be quickly and efliciently made by thebinding screws instead of being soldered and taped, as at present. Thisprovision of a centrally perforated in- Specification of Letters Patent.

sulating rosette is an essential feature of the invention enabling arosette with terminal plates and binding screws to be made use of incombination with a chandelier or the like.

To facilitate the use of the screw driver in proximity to the centralstem of the chandelier the under surface of the insulator 6 to which theterminal plates are secured is angled as a cone or prism thus directingthe axes of the screws away from the suspension rod and affording roomfor the convenient use of a screw driver in securing the wires. Theinsulator 6 is also made with a flange 12 projecting outward beyond theterminal plates and having portions removed at 13 on opposite sides forthe passage of the wires to the terminal binding screws. This flange ispreferably downwardly angled, as shown in the drawings, to form a dripedge for any moisture that may condense on the surface of the insulator.After the connections are made a conical guard 14, preferably made ofthin nonconducting fiber board, is secured in contact with the flange ofthe insulator and thus effectively incloses the terminal connections.Thereafter the ornamental bell canopy 15 which was moved down thetubular casing 5 while the connections were being made may be moved upagain into contact with the ceiling.

I am aware that prior to my invention insulating rosettes of variousforms have been used having terminal plates by which service wires maybe connected to the wires of a room circuit but within my knowledge noinsulating rosette has been provided with a central aperture to receivea lamp suspension rod nor within my knowledge have the binding screwsbeen angled outward from the suspension rod, nor an insulating rosettehaving the downwardly angled protecting flange having port-ions removedfor the passage of the service wires nor the conical protecting shieldof non-conducting fiber board.

Having now particularly described my invention and drawn attention tothe advantages of the several features, I hereby declare that what Iclaim as new and desire to be protected in by Letters Patent, is:

1. An insulating rosette for an electric lamp attachment comprising abody of insulating material centrally perforated to receive the lampsupport said body being provided with terminal plates and binding screwsfor the attachment of the line service and lamp wires, and a conicalguard of non-conducting fiber board bent around the central stem of thesupport and inclosing the terminal connections.

2. An insulating rosette for an electric lamp attachment comprising acentral body of insulating material, said body having a centralaperture, the under face of said body being coni-formed, downwardlyinclined radial wings formed with said body, binding plates secured tosaid wings and projecting on to the coni-form face of said body, bindingscrews threaded into said plates, said body having recesses into whichsaid binding screws project, said binding screws lying at a downward andoutward inclination to the axial line of said body aperture. I

3. In an electric light attachment a central disk-like body ofinsulating material, having its under face coni-formed and provided withradially projecting downwardly inclined wings, plates held on saidconiformed surface of said body portion, and having ears projected tolie under and against the respective wing surface, securing screws passthrough said wings into said ears to retain said plates, and bindingscrews threaded into said plates and lying normal to the coni-formedsurface, said body portion having recesses to receive the respectivebinding screws.

4:. In an electric light attachment a central disk-like body ofinsulating material, having its under face coni-formed and provided withradially projecting downwardly inclined wings, plates held on saidconiformed surface of said body portion, and having ears projected tolie under and against the respective wing surfaces, securing screws passthrough said wings into said ears to retain said plates, and bindingscrews threaded into said plates and lying normal to the coni-formedsurface, said body portion having recesses to receive the respectivebinding screws, means for mounting said body portion on an electriclight fixture, a conical guard of nonconducting material mounted on saidfixture below and in close proximity to said body and beneath the same,and a canopy mounted on said fixture to inclose the aforesaid guard andbody together with the body carried parts.

In testimony whereof I have signedgny name to this specification in thepresence of two subscribing witnesses.
